Re: [CentOS] MIgrate/Upgrade from Centos 5.4 32bit to Centos 5.4 64bit
Thanks all for the help. I will boot in rescue mode, then rename all directories, install the 64bit version and then restore all the files. I have been upgrading this server in redhat 4.2 i386, so this time there is a need for platform upgrade also. It has been a long way from a P2 to a Core2Duo Quad ;) Regards, Oliver -- Oliver Schulze L. http://tinymailto.com/oliver El 05/01/10 17:09, Robert Heller escribió: At Tue, 5 Jan 2010 11:26:32 -0800 CentOS mailing listcentos@centos.org wrote: On Tue, Jan 5, 2010 at 11:24 AM, MHRmhullr...@gmail.com wrote: On Tue, Jan 5, 2010 at 7:46 AM, Oliver Schulze L.oli...@samera.com.py wrote: Hi, It is posible to do a simple procedure to upgrade a Centos 5.4 32bits (i686) to a Centos 5.4 64bits(x32_64)? I was thinking about an upgrade or install without formating. I will have a current backup before doing it. Any advice/tips is welcome. I *strongly* doubt it. When you go from 32 to 64 bit systems, you are essentially replacing the kernel and (at least) about 90% of the standard libraries. I am willing to bet that this mandates an installation. For the record, I've never tried it. When I put CentOS on my machine, I already had a 64-bit CPU and I never seriously considered NOT using the 64-bit install. HTH. mhr Sorry - PS: IIRC, you don't _have_ to format your disks to install over what's on them - check the installation options when you get that far and read through them carefully. You should be able to re-use existing partitions, but I can't remember whether that *requires* reformatting them - I've just always done that (reformat them). You really should/ought to reformat /, /usr, and /var. /boot and /home don't need to be reformated (leaving /boot alone allows for multi-OS version booting, eg CentOS 4 and CentOS 5 or Ubuntu and CentOS or CentOS and Fedora, etc.). The installer will be unhappy about NOT reformatting /, /usr, or /var. It will warn about not reformatting /boot -- this is generally OK though. It will NOT complain about not reformatting /home or any other random non-system file system you might have (I do things like have a dedicated /mp3s file system on my laptop for example). Unlike the *default* file system setup, which only creates /boot and / file systems, it is *strongly* recomended to instead create separate /boot, /, and /home file systems (at least these three -- separating out /usr and/or /var might make sense under some situations, esp. servers) -- this allows updates, multi-OS, and recovery without having to make an explicit backup (although, having backups is still recomended!). ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Writable Centos LiveCD on Embeded Linux?
Hi Johnny, I was exploring some options to make the embeded platform boot faster. Right now I'm using ext2 partitions(ext3 use more I/O), but when it is shutdown improperly it takes a little to boot(it runs fsck). I was thinking that the LiveCD will help boot faster when the power goes off, but now I realize that the ext2 solution will be better. Thanks for all comments, Oliver Johnny Hughes wrote: OK ... what would be the benefit of booting and updating the livecd as compared to just installing and updating CentOS on the flash. There is nothing special about the RPMS on the LiveCD as compared to regular CentOS. The only possible thing I see as an advantage would be the fact that the OS was NOT WRITABLE .. however, by rolling in the overlay feature, you would be over riding that.

Re: [CentOS] Writable Centos LiveCD on Embeded Linux?
Hi Stephen, thanks for answering. I'm trying to see if I can get a router using an embeded platform, alix in this case. Since the Alix platform is getting more powerfull and the 1GB compatch flash is also getting cheaper, I was think in createing a full Centos distro booting in that platform. Will read more about the overlay feature and see if it will do the job for me. But maybe I will go back to have an ext2 partition and don't write to it. I like the LiveCD option because of the fast (no fsck) boot feature Regards, Oliver Stephen John Smoogen wrote: On Sun, Aug 10, 2008 at 1:19 PM, Oliver Schulze L.

And the overlay solution will require too much space. For the live Cd that is about your only choise. The overlay will not grow.. it will eventually fill up, but if you are making that many changes in an embedded environment you really need to think about why you aren't doing a complete reflush of the SSD -- Oliver Schulze L.

Re: [CentOS] PHP 5.2
I hope the gophp5.org problem will not repeat in php6. I mean, I would be nice to have a more firendly upgrade plan, or maybe a multi core/version php that supports both php4 or php5. I agree that the move should be done toward 5.2, and also understand the problem the hosting providers are having and will have when php6 is launched. Dropping backward compatibility is always an issue ... Oliver John Thomas wrote: To me, there seems to be growing support to requiring PHP 5.2 within the next year, see http://www.gophp5.org/ .
